To 'olif who-m it conce/m Be it known that I, Riemann Scritta-Mann,

. vice ionl uns having a pointingtelescope and. an. o ervation.telescope rigidly connected thereto, but with'separate eye ieces soarrangedv that each may he use sep arately by different persons. 'Suchsighting devices are preferably used. on guns that serve for firingagainst very rapidlymoving targets, airships for instance, in order toavoid all command transmission and the consequent retardationl infiring.

The object of the invention is to provide a sighting device of the abovementioned kind which confers this character tothe gun, on which it isused, that the gun may be utilized equally well in defense againstairships` as also in ordinary field service; and that the device, by aparticularly compact construction, guarantees great convenience in itsuse.

The accompanying drawings represent one embodiment of the invent-ionwhere- Figure l shows a side nelevation of Aa gun sight and Fig. 2, asection on line 2 2 of' of Fig. 1, seen from above.

A is the elevating bar, upon which is'fastened a seat B for receiving apanoramicv telescope C. The panoramic telescope C, which serves aspointing telescope, consists, as usual, of a reflector prism c1 (Fig.2), revoluhle around its horizontal axis, and seated in a reflectorhousing c2 which is turnable around its vertical axis. The panoramictelescope can be pushed down from above into the seat B and locked fasttherein; and the holder is then in such a' position upon the elevatingIbar, that the eye piece c3 ofthe panoramic telescope stands at rightangles Lo the plane of elevation.

The observation telescope D is directly connected with the panoramictelescope in such a manner, that the middle part (Il of its lio-usingand the reflector housing@2 of the panoramic telescope constitute onepiece. The sight line cl2 of the observation telescope (Fig. Q) issituated to one side of the sight line c4 of the panoramic telescope andruns parallel therewith, when the r'ziicctoi prism. cvis set, so thatthe sight line c4 lies 1n its'middle elevation, perpendicular to theturning axis of the reflector housing c2. The eye piece holder d3 (Fig.l) of the ohservation telescope is inclined in an upward direction toobtain aI convenient view.

' The use of the above described sighting device in. firing againstairships is. accomp'lishedV 1n; this manner, customary withl Asightingdevices of this kind,l that the gun pointer always keeps the line ofsight on the target by means of the elevating and traversmgfgea-rsof thegun, while the oh server adjusts the sighting device for'elevation anddirection and' also does the firing. Itis for this reason desirable, inthe interest of a most convenient handling of the sight ing device, that-the eye piece of the pointing telescope issituated as low as possibleand the eye piece of the observation telescope lies comparatively high.A

The use of a panoramic telescope. as pointing makes it now possible toobtain. such favorable positions of both eye pieceswith' fixed directconnection of the. two telescopes; because of the peculiarly largedistance between the eye piece and the refigctor head of the panoramictelescope, being ample to avoid all interference between the observerand the pointer.' If in place of a panoramicv telescope any other kindof telescope had been chosen, a contracted arrangement of pointing and,oh-

servation telescopes with an especial con-A necting piece would berequired. By the omission of any such connecting piece, the

sighting device, builtin accordance with. the receives a particularly lpresent invention, compact construction. As a. consequence of the fixeddirect connection between the pointing Vand the observation telescope,an additional advantage is furthermore attained, namely this, that theparallelism of the two sight lines is to a high degree assured, whichparallelism otherwise may easily he destroyed in the separatearrangement of the two telescopes,A for instance by the wearing away ofthe adjoining surfaces l at the place of connection. Still anotheradvantage is gained by the use of a panoramic telescope, namely that thesight lines of the pointing telescope and the observation telescope, arebothl situated at' approximately the same height, although the twoeye-pieces are larranged at'altogether different heights;

changing its optical which so far is advantageous,that the sightlopening jin the protective shield may be made smalleignnder otherwisesimilar conditions. The panoramic telescope is furthermore the onlytelescope that may, without construction, be Var- -'ranged onthe`ight-carrier in suoliv a inanner, that the eye-piece takes va-positionat right angles Vto the elevating plane, which makes the ,sightingcomfortable 'at any ele- ,-va tion. Thesev advantages confer upon a y:--gfiiin provided with the described-sighting deyice, Vsuch qualitiesthat make it particu larly suitable as agun for defense againstauirships.y In' `consequence of the employy...ment o'iavlpanoramictelescope as pointing v providesa field l yfiring against airsliips,.will experience no with va a panoramictelescope having its eyelimitation on account of :the loss of parallelism betweenvthe tivosight'linesd2 and :4 through the displacement ofthe reflector prismc1 inelevationas Va consequence of ther connection between the observationtelescope with the refiector housiiigazofl the lpanoramic telescope,which housing then remains stationary. Suchv a displacement will, namelyonly be required during indirect firing and only in firing againsttargets on the field, whenfthe observation telescope remains unused, asdescribed above. lt is, for thisY reason, practicable to fixedly conneetvthehousing of the observation telescope part of the housin'g'2 of thepanoramic telescope.
